In a way that doesn't make any significant changes in
rectangle--duplicate-right, for example.

> The bulk of the change is in tests.

That's not the part which bothers me, obviously.

> It is the exact equivalent to Juri's change to duplicate-line, but that one actually had a bigger footprint; this change only affects duplicate-dwim and nothing else.

The difference is that (a) duplicate-line was a feature which was
explicitly requested by the bug report which caused its
implementation, and (b) the changes for duplicate-line were much
simpler and easier to reason about.

> If you like, I could try splitting the change into smaller parts.

I'm not sure I understand what would that accomplish.
